Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed July 29, 1908. Serial Ho. 445,967.

To. all whom it may concern:

lie it known that we, Jon HOFFHIN-E and .clcmimn F. HARRIMAN, citizens of the United Stet-es, residing at Omaha, in the county of Douglas and State of Nebraska, have, iii-- vented certain new and useful Improvements in Stills, of which the following is a full, clear, and exact description, such as will on- .abie' others skilled in the artto which it appertains to make and use the same This invention relates'to stills.

@no of the objects thereof is, to provide is device of the above type of simple, cheap, and strong construction and having all parts so compactly disposed as to consume small space andyet be of large capacity. I

Another object is to provide a device of the above type whichlshall' be substantially automatic in action.

Another object is to provide a device of the type first mentioned characterized by efiicientsnd economical running qualities.

Another object is toprovide a still so formed as to he reudily cleaned and in which the chance of contamination of the distillate isroduced, to a minimum. (Ether objects will he ii in part pointed out liez'ei' The invention accordingly consists in the features of construction, combinations of obvious and will be exemplified in the construction hereinafter set forth, and the scope of the application ofiivhich will be indicated in the following claim. Y

"In the accompanying drawings, wherein. is show-n one of various possible embodiment's'of this invention,'l igure 1 is a side elevation thereof, partially in section in. or

der' to show the construction more -eclearly Fig; 2' is a. plan view of a supporting frame or holder; Fig. 3 is a detail view of a sup- "portling block; 4 is aside elevation of a j'condensing coil and associated parts; Fi 5 'Fised-et'ail view ofa coil support; Fig. 61s a sectional view taken substantially along the line w view taken substantially along the line c y invention .miore readily and fully understood, it may here be noted that in the'use of many stills there is a tendency to contamination by the carryingover from the boiler of small particles of the fluid acted u on in a liquid instead of vaporous-form. his is especially the case when the boiling is violent and is especially annoying when a high degree of'puri'ty is desired in the distillate. It may also be noted that if a large output is desired in apparatus of the general nature dealt with in this invention, a large outlay of heat is required, which, unless the distil lute 'is innnediately used in warm condition, is largely thrown away, being taken up in the latent heat of vaporization and carried all by the cooling water as the" distillate c on- "enses.

Anothen'feeture which may be noted is the fact that in distilli'nga liquid which leaves-a residue or scale upon the heating surfaee,"unless means are provided whereby ready access can be had to all parts'of the device this deposit or scale will gradually reduce the efficiency of the apparatus.

The above and, other-defects are done away with inconstructionsof the nature of that hereinafter described.

, l teferringnnow to the accompanying :lra wings, there is shown in Figrle shelter easing '1 having fitted therein a head. 2,

fiang'ed'ns at 3, and riveted in place, as shownat 33 in said figure. Upon thls head is laid a plate 4 which he's mounted thereon a supporting spider or bracket 5, best shown in Fig. 5 of the drawings, theendszof which rest in the severallooks 6. Upon this spider is afiat heatin coil 7, preferably of copper, one end of w llCll' lends to a" nipple 8 and thev other end to a nipple 9, both mounted in-thewall ,of the casing and form ing a" tight joint therewith. v

Removably. secured to the upper" end of the casing 1, as byflangfes l0 and bolts 11 is a cap or head 12 forfning a, passage 13 leading to a nipple 14 in the head '15 of a second casing-or receptacle l6.'

Thesefbrackets 18 are pre stably formed, as shown, of sheet metal ahdserve tohold-th'e'coil in properreliitmn with respectito the walls of the casing, as well as. to hold the several turns of the cod pro erly spaced one from another.

The upper ortionof the casing 16, which forms a 00nd of the casing," 1, which forms a boiler, are connected one with another, as at 2-7, and

' there is provided to the condenser an inletjconnection 28.

The head 12 is provided with screens 29 and 30 serially'disposed, as shown, in the passage of the vapor passin from the boiler and adapted, even with t e' most violent ebullition in the latter to prevent any particles of liquid. passing to, the cooling coil.

There is also proxdded' in head 12,101 at .any other suitable point, a check valve 31 adapt edto admit am from without, in the event of a vacuum forming at any point in the apparatus, and thus relieve thesame from strain. 'There' is also provided at 32- an outlet port normally held closed, as b' a cap, but adapted to be opened if it is desired to wash out the interior of the boiler.

It may here bef noted that the term vapor is used throughoutin a broad sense to denote any fluid passing over. from the boiler to the condenser.

The operation of the abovedescribed embodiment of this invention is substantially as 'follo'ws-z The ni ple' S' is connected to "any desired source 0 steam supply, and the inlet 28'connected with the source of supply of the liquid which is to be distilled, in the "present case assumed to be water.- These two inlets are adjusted as to admit water through h'econdenser and-connection 2'1 at ust such rate as tomaintain the level in the boiler justabove the heatin coil 7 and as y to substantially condense aj1, we ave shown an 'ordinah'y 4 i of the steam passln into the latter member." :In Fig.

As many changes could be made in the above construction and many apparently widely different embodiments of this inven "tion'could be made withoutdeparting from the scope thereof, it is intended that all matter contained inthe above description or shown in the accompanying -drawings shall be interpreted as illustrative and not in a.
